Prompt (Single Continuous Frame – No Cuts)
A dimly lit underground parking garage at night. Flickering fluorescent lights cast uneven shadows across concrete pillars. The atmosphere is tense and quiet.
The camera slowly tracks backward in a single continuous motion, facing a man who is walking cautiously toward the camera. He looks alert and slightly anxious, glancing around as if he feels someone is watching him.
As he walks, the lights above him begin to flicker one by one in sequence behind him only (important: lights switch off progressively in the direction he came from, not ahead of him).
A faint shadow briefly appears between the pillars in the background, always staying behind him, never crossing in front. The man senses something, stops for a moment, and turns slightly but sees nothing clearly.
The camera continues moving backward smoothly, maintaining distance. The sound of soft footsteps echoes but they do not match his pace.
Final seconds:
One last light flickers off behind him, plunging part of the garage into darkness. As the frame settles, a vague human-like silhouette is visible far in the background, partially hidden in shadow stationary, watching.
Important Direction (to avoid mistakes)
The camera must remain a single continuous backward tracking shot (no cuts)
The mysterious presence stays behind the man at all times, never appearing in front
Lighting flickers in a clear directional sequence (back to deeper darkness)
No jump scares tension is built through movement, sound, and shadows
The man never runs; he remains cautious and controlled
Mood / Feel
Suspenseful, tense, mysterious, slow burn thriller with psychological unease.
